ESPINOSA-RODRIGUEZ, M.A.  and  FALL, C.. Optimization of the Production of Sludge in an Activated Sludge System Through the Calibration of the ASM1 Model. Ing. invest. y tecnol. [online]. 2015, vol.16, n.1, pp.93-104. ISSN 2594-0732.

Recently several protocols have been proposed for the calibration the ASM1 model and each one of them emphasizes obtaining a good adjustment in the production of sludge. Precisely here is where the discrepancies are evaluated and adjustments made to data, through a mass balance. The objective of this work was to conduct first a balance of flows in the wastewater treatment plant "Dulces Nombres" in Monterrey, Nuevo Leon, Mexico, and then adjust them until closing properly the mass balance for the total phosphorus, total suspended solids, and inorganic suspended solids (ISS). On might say that to calibrate the biological model was important to determine reliably the flow of sludge (Q_WAS) since on it depends the cell retention mean time (θ_C) in the reactor; this was accomplished successfully through the balance of the ISS and using of GPS-X software for the simulation of scenarios of optimization.

Keywords : ASM1 model; calibration; sludge purge; flows balance; mass balance.
